LANSING KELLOGG, OF RAVENNA, OHIO.

CHEESE-PRESS.

Specification of Letters Patent No. 6,101, dated February 6, 1849.

T 0 all fao/0m t may concern Be it known that I, LANSING KnLLoGe, ofRavenna, in the county of Portage and State ot Ohio, have inventedcertain new and useful Improvements in the Cheese-Press, of which thefollowing is a full and exact description, reference being had to theannexed drawings of the same, making part of this speciication, inwhich- Figure 1 is a perspective view, Fig. 2 is a section taken througha part of the post B in the line m and Fig. 3 is an elevation of thepart of the post in front of the section.

.The nature of my invention and improvement consists in placing betweena pair of toggle j o-int levers, and a screw which operates therein, anelliptical or other spring in such a'manner that it is compressed by thetorce applied by the screw to the levers, and by its ei'fort to expandagain has the eect of continuing the pressure of the levers upon thecheese or whatever subst-ance is placed between them and the platenafter the screw has ceased to operate. The screw may also be so arrangedas merely to be used for the purpose of compressing the spring whichinthis case would alone act upon the toggle joint to produce the necessarycompression. The combined action of the toggle oint and spring producesa steady, continuous, and moderate pressure which'seems to be thepeculiar action best adapted to the pressing of cheese, which by toosudden and violent pressure is forced through the cloth and hoop in'which it is contained, and it not long enough continued the whey is leftin it which materially deteriorates its quality.

In the accompanying drawings A is the platform of the press, it is ofany suitable size, and is most conveniently made of thick plank, uponthis platform the two uprights B B are erected; between these uprightsthe platen a is placed, also the transverse pieces o in which mortisesare made to form guides for the piston C, t-he binding beam D on whichis the point of support for the levers, and likewise the guide piece Zin which a slot is made to guide the toggle joint levers E E and springF in their` lateral movement.

The screw z' compresses the spring F by forcing it against the togglejoint e being attached to it by a swivel joint s. The nut in which thescrew turns, and which is of course its point of support is in the postB, and turns on an axis n as shown in Figs. 2 and 3.

The spring may be made of any approved form but I prefer an elliptic ofthe kind in common use for carriages.

The several parts of this machine may be made of any material which inthe view of the constructor is most suitable 0r convenient.

` The operation of this press being an alogous to that of all othersupon the toggle' joint principle and quite obvious from an inspection ofthe drawing, I have not deemed a detailed description of the same here,to be necessary.

That I claim as my invention and desire to secure by Letters Patent, is-

The combination of the spring, with the screw and toggle joint as hereinset forth, or in any other substantially similar manner by which thesame effects are produced.

In testimony whereof I have hereunto set my hand and aiiiXed my seal,this seventh day of October A. D. 1848.
